Was bedeutet der Fehlercode?
The engine control module (ECM) drives the injectors through two integrated high-power output stages. This code applies to cylinder 4 and is set when the module detects a faulty signal while the engine is running. It gives no further fault type and can be a knock-on fault from another fault in the injectors or fuel system, which should be dealt with first.
Mögliche Ursachen
- Knock-on fault from a fault detected by another trouble code test for the injectors and/or fuel system
- Damaged injector
Was Sie tun können
- 1Check that the fuses are intact. The locations are in the owner's manual or on the fuse box cover.
- 2Go through the other stored codes. Deal with any faults on the injectors or fuel system first, because the cylinder 4 code may be a knock-on from them.
- 3With a diagnostic tool, the injector for cylinder 4 can be activated. Listen for a click and compare with the other cylinders.
- 4Check that the connector to the cylinder 4 injector is secure and free from corrosion.
- 5If the fault returns, have a workshop with diagnostic equipment check the cylinder 4 injector.
